    Persistent schizophrenias and delusional disorders are classified as primary psychiatric pathologies amongst the elderly. It is crucial to distinguish them from secondary psychotic disorders associated with physical illnesses, such as acute confusion and psychotic symptoms caused by dementia or other somatic pathologies. Employing the concept of a primary psychiatric disorder occurring in an elderly patient is not simple, and each term used to define the concept refers back to an array of various criteria in clinical, psychological, biological, neurological, and cognitive fields. What about very late-onset schizophrenia, occurring after the age of 60 years, for instance? Is this a primary psychiatric illness occurring very late or a secondary pathology caused by brain disease, particularly a degenerative one? Studies reveal controversial results and it is still being debated as to whether the disease has neurodevelopmental or neurodegenerative causes. Due to the variable symptoms and psychiatric, somatic, and cognitive comorbidities associated with psychosis in elderly patients, patient healthcare must not be limited to prescribing an antipsychotic. Once it has been determined whether the psychosis is secondary or primary (old-agerelated schizophrenia, late-onset or very late-onset schizophrenia, or late-onset delusional disorder), an aetiological or symptomatic treatment must follow, including a psychotherapeutic approach, close surveillance of the drug treatment and its potential side-effects, rehabilitation steps through community-based care, and psychoeducational support for the family and other professionals in charge of the patient. Our article's aim has been restricted to summarising our understanding regarding late-onset schizophrenias and delusional disorders amongst the elderly

    Metabolic physiology of the Mayan cichlid fish (Mayaheros uropthalmus): Re-examination of classification as an oxyconformer

    Artículo científico JCR Q1The Mayan cichlid (Mayaheros uropthalmus) is a freshwater fish inhabiting warm, potentially hypoxic and/or brackish waters, in Mexico and Central America. Despite its description as highly hypoxia tolerant, M. uropthalmus has been classified physiologically as an ‘oxyconformer’, which would place it in a very small (and shrinking) category of fishes that purportedly cannot maintain oxygen consumption (ṀO2) as ambient PO2 falls. However, hypoxia tolerance is often associated with strong oxyregulation, not oxyconformation as described for M. uropthalmus. To resolve these inconsistencies, we measured ṀO2, the ambient PO2 at which ṀO2 begins to decline as PO2 falls (PCrit), and gill ventilation rate (fG) in the Mayan cichlid. Variables were measured at 23o, 28 o and 33 °C and temperature sensitivity (Q10) calculated for each function. ṀO2 at air saturation was 2.9 ± 0.2, 4.3 ± 0.4, and 5.9 ± 0.3 μmol O2/g/h at 23o, 28o and 33 °C, respectively. PCrits were low at 2.6 ± 0.8 kPa, 3.2 ± 0.8 kPa and 4.7 ± 0.9 kPa at 23o, 28o and 33 °C, respectively. Q10 values for ṀO2 were 2.56 ± 0.21 (23- 28 °C), 1.89 ± 0.15 (28-33 °C) and 2.2 ± 0.1 (full temperature range of 23-33 °C), suggesting overall Q10s typical for tropical freshwater fish. fG was 39 ± 3, 45 ± 4, and 53 ± 6 breaths/min at 23o, 28o and 33 °C, respectively, and increase 2–3 fold in severe hypoxia at each temperature. Experiments employing hyperoxia up to 35 kPa indicate a strong ‘hypoxic drive’ for gill ventilation. Collectively, these data show that, in contrast to a previous characterization, the Mayan cichlid is a strong oxyregulator exhibiting attributes (e.g. very low PCrit) typical of very hypoxia-tolerant fishes.US National Science Foundation UAEMex PRODEP-SE

    Bone metastasis; MiRNAs; Prostate cancerMetàstasi òssia; MiRNAs; Càncer de pròstataMetástasis ósea; MiRNAs; Cáncer de próstataAbout 70% of advanced-stage prostate cancer (PCa) patients will experience bone metastasis, which severely affects patients’ quality of life and progresses to lethal PCa in most cases. Hence, understanding the molecular heterogeneity of PCa cell populations and the signaling pathways associated with bone tropism is crucial. For this purpose, we generated an animal model with high penetrance to metastasize to bone using an intracardiac percutaneous injection of PC3 cells to identify PCa metastasis-promoting factors. Using genomic high-throughput analysis we identified a miRNA signature involved in bone metastasis that also presents potential as a biomarker of PCa progression in human samples. In particular, the downregulation of miR-135b favored the incidence of bone metastases by significantly increasing PCa cells’ migratory capacity. Moreover, the PLAG1, JAKMIP2, PDGFA, and VTI1b target genes were identified as potential mediators of miR-135b’s role in the dissemination to bone. In this study, we provide a genomic signature involved in PCa bone growth, contributing to a better understanding of the mechanisms responsible for this process. In the future, our results could ultimately translate into promising new therapeutic targets for the treatment of lethal PCa.The study was supported by grants CPII18/00027 and PI18/01017 to A.S.; PI17/02248 to J.M.; grants PI09/00496, PI13/00173 and postdoctoral fellowship CD12/00475 of Instituto de Salud Carlos III (ISCIII), pre-doctoral fellowship of Vall d’Hebron Research Institute (VHIR), postdoctoral fellowship PERIS of Departament de Salut Govern de Catalunya to M.O.; BBVA and PID2019-104948RB-100 to M.G.

    Inherited retinal diseases (IRDs), defined by dysfunction or progressive loss of photoreceptors, are disorders characterized by elevated heterogeneity, both at the clinical and genetic levels. Our main goal was to address the genetic landscape of IRD in the largest cohort of Spanish patients reported to date. A retrospective hospital-based cross-sectional study was carried out on 6089 IRD affected individuals (from 4403 unrelated families), referred for genetic testing from all the Spanish autonomous communities. Clinical, demographic and familiar data were collected from each patient, including family pedigree, age of appearance of visual symptoms, presence of any systemic findings and geographical origin. Genetic studies were performed to the 3951 families with available DNA using different molecular techniques. Overall, 53.2% (2100/3951) of the studied families were genetically characterized, and 1549 different likely causative variants in 142 genes were identified. The most common phenotype encountered is retinitis pigmentosa (RP) (55.6% of families, 2447/4403). The most recurrently mutated genes were PRPH2, ABCA4 and RS1 in autosomal dominant (AD), autosomal recessive (AR) and X-linked (XL) NON-RP cases, respectively; RHO, USH2A and RPGR in AD, AR and XL for non-syndromic RP; and USH2A and MYO7A in syndromic IRD. Pathogenic variants c.3386G > T (p.Arg1129Leu) in ABCA4 and c.2276G > T (p.Cys759Phe) in USH2A were the most frequent variants identified. Our study provides the general landscape for IRD in Spain, reporting the largest cohort ever presented. Our results have important implications for genetic diagnosis, counselling and new therapeutic strategies to both the Spanish population and other related populations.This work was supported by the Instituto de Salud Carlos III (ISCIII) of the Spanish Ministry of Health (FIS; PI16/00425 and PI19/00321), Centro de Investigación Biomédica en Red Enfermedades Raras (CIBERER, 06/07/0036), IIS-FJD BioBank (PT13/0010/0012), Comunidad de Madrid (CAM, RAREGenomics Project, B2017/BMD-3721), European Regional Development Fund (FEDER), the Organización Nacional de Ciegos Españoles (ONCE), Fundación Ramón Areces, Fundación Conchita Rábago and the University Chair UAM-IIS-FJD of Genomic Medicine.

    The European Hematology Association Roadmap for European Hematology Research: a consensus document

    Get PDF
    The European Hematology Association (EHA) Roadmap for European Hematology Research highlights major achievements in diagnosis and treatment of blood disorders and identifies the greatest unmet clinical and scientific needs in those areas to enable better funded, more focused European hematology research. Initiated by the EHA, around 300 experts contributed to the consensus document, which will help European policy makers, research funders, research organizations, researchers, and patient groups make better informed decisions on hematology research. It also aims to raise public awareness of the burden of blood disorders on European society, which purely in economic terms is estimated at €23 billion per year, a level of cost that is not matched in current European hematology research funding. In recent decades, hematology research has improved our fundamental understanding of the biology of blood disorders, and has improved diagnostics and treatments, sometimes in revolutionary ways. This progress highlights the potential of focused basic research programs such as this EHA Roadmap. The EHA Roadmap identifies nine ‘sections’ in hematology: normal hematopoiesis, malignant lymphoid and myeloid diseases, anemias and related diseases, platelet disorders, blood coagulation and hemostatic disorders, transfusion medicine, infections in hematology, and hematopoietic stem cell transplantation. These sections span 60 smaller groups of diseases or disorders. The EHA Roadmap identifies priorities and needs across the field of hematology, including those to develop targeted therapies based on genomic profiling and chemical biology, to eradicate minimal residual malignant disease, and to develop cellular immunotherapies, combination treatments, gene therapies, hematopoietic stem cell treatments, and treatments that are better tolerated by elderly patients

    Why Are Outcomes Different for Registry Patients Enrolled Prospectively and Retrospectively? Insights from the Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF).

    Background: Retrospective and prospective observational studies are designed to reflect real-world evidence on clinical practice, but can yield conflicting results. The GARFIELD-AF Registry includes both methods of enrolment and allows analysis of differences in patient characteristics and outcomes that may result. Methods and Results: Patients with atrial fibrillation (AF) and ≥1 risk factor for stroke at diagnosis of AF were recruited either retrospectively (n = 5069) or prospectively (n = 5501) from 19 countries and then followed prospectively. The retrospectively enrolled cohort comprised patients with established AF (for a least 6, and up to 24 months before enrolment), who were identified retrospectively (and baseline and partial follow-up data were collected from the emedical records) and then followed prospectively between 0-18 months (such that the total time of follow-up was 24 months; data collection Dec-2009 and Oct-2010). In the prospectively enrolled cohort, patients with newly diagnosed AF (≤6 weeks after diagnosis) were recruited between Mar-2010 and Oct-2011 and were followed for 24 months after enrolment. Differences between the cohorts were observed in clinical characteristics, including type of AF, stroke prevention strategies, and event rates. More patients in the retrospectively identified cohort received vitamin K antagonists (62.1% vs. 53.2%) and fewer received non-vitamin K oral anticoagulants (1.8% vs . 4.2%). All-cause mortality rates per 100 person-years during the prospective follow-up (starting the first study visit up to 1 year) were significantly lower in the retrospective than prospectively identified cohort (3.04 [95% CI 2.51 to 3.67] vs . 4.05 [95% CI 3.53 to 4.63]; p = 0.016). Conclusions: Interpretations of data from registries that aim to evaluate the characteristics and outcomes of patients with AF must take account of differences in registry design and the impact of recall bias and survivorship bias that is incurred with retrospective enrolment.
